THE TEAM SEARCHES FOR AN HIV POSITIVE PREGNANT WOMAN WHO DISAPPEARS AFTER GOING FOR AN ULTRA-SOUND WITH HER HUSBAND, ON "WITHOUT A TRACE," THURSDAY, APRIL 13

Tony Award Winner and Grammy Award Nominee Betty Buckley ("Cats," "Oz," "Eight Is Enough") Guest Stars

"Expectations" -- The team searches for an HIV positive pregnant woman who vanished moments after she and her husband saw the ultra-sound of their healthy 8 �-month-old fetus, on WITHOUT A TRACE, Thursday, April 13 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Rosemary Rodriguez directed the episode written by David Rapp.

Tony Award winner and Grammy Award nominee Betty Buckley ("Cats," "Oz," "Eight Is Enough") guest stars as the missing woman's mother.

The team members remain wary of Megan's husband, Brian, who allegedly left for a business trip after the ultra-sound. Their suspicions are heightened when they learn that he had a brief affair last year after Megan was diagnosed with HIV, which she contracted from a previous relationship. Brian admits that it's not easy for either of them to live with her HIV, but they're working through it and, after much thought, chose to start a family. He suggests questioning a blood technician who upset Megan by chastising her for putting her child at risk by choosing to become pregnant with HIV. They also investigate whether Megan's disappearance is connected to an attempted infant abduction at the same hospital three weeks prior and look into the relevance of her last incoming cell phone call from a detention center.
